Our invention relates to suspension means for vehicles, particularlyautomotiveand similar vehicles, and has essentially for'its object tosubstitute for the'usual metal springs, air cushions interposed betweenthe frame and the wheel axles.

The invention also comprises other objects as will hereinafter appear. 7I v f In order that the invention may be clearly understood and readilycarried into practice,

it has been illustrated by way of example in the accompanying drawingsas applied to a car of the Ford type.

In these drawings Fig. 1 is an elevational front view of the front wheelensemble embodying the invention, the left hand side of the figureshowing the spring suspension now used.

Flg. 2 is a View toward one of the front 2 wheels as seen from the rightin Fig. 1.

Fig. 3 is a similar view as Fig. 1 showing the rear wheel ensemble,while Fig. 4 is a similar view as Fig. 2 toward one of the rear wheelsas seen from the left in Fig. 2.

In the drawing 1 indicates the front axle of a Ford car, and 2 is thefront cross-beam of its frame. According to the present in vention, theusual metal springs are replaced by an air chamber 4 .which is placedand supported between the axle 1 and frame 2 in any suitable manner. Theair-chamber l'i's provided with a suitable valve (not shown) ofwell-known construction whereby the pressure in the air-chamber may beadjusted at 5 will, thus securing greater or lesser elasticity in thevehicle, as desired. 1

As shown, the outer jacket 3 of the airchamber bears with its bottomportion againsta board adequately secured to wheel axle 1,

said board having also flanges engaging the beaded edges of outer jacket3. A double toggle is provided at each side of the frame held thereon bymeans of stirrups 6 to which .are pivotally connected the toggle-membersa5 7 which in turn are pivotally connected to the members 9 by means ofpins 8, the other end of members 9 being pivotally connected to stirrups10 rigidly secured to the axle 1. In order to prevent undesirabledisplacements of the frame relative to axle 1', they are pro-198,7'7Land in Argentina Aprirm; i927.

videdat the front portion ofthe vehicleone ortwo pairsoftogglesjconnecting the frame to the front axle which also permit of acertain degree oftiltiofthe frame relative to the axle. The said togglespreferably arc mounted with their upper portions in a guide 11 withinwhich is houseda cylindrical member 13 to which is linked, at lt, theupper end of the links 15 connectedin turn to links 17 by means of pins16 the' latter. being pivotally connected withtheir lower ends tostirrups 18 secured to theax'le l or to the lower bearing member 5. Withits upper part the outer jacket of the airicushion bears againsta board12 adequately secured to the underside of the front cross-beam 2 of theframe. I

As concerns the rear wheels, the arrangement used is similar tothat'justdescribed and there may be employed one, two or more 7 air chambersdepending on the particular character and type of the vehicle. 3

As shown, 19 is the rear axle and 20 is the frame of the vehicle to thebottom ofwhich is secured a board 20 below which is situated I the outerjacket 21 of the air chamber. Said jacket is engaged by the flanges 22of a plate 23 secured. to the rear axle b-y means of the clampingmembers24. The rear axle l9 and underframe' 20 arev connected togetherby g means of a double toggle pivotally connected ;to the former, withits lower end, bymeans of pivot 25 of links 26 pivoted to the links 28by means of a pin, the latter being pivoted to '3 the frame by means ofthe pivotal connec- 5 tion 29. The pivot pin of the links is indicatedat 27 In a similar manner and disposed at substantially right angles, isa clamping member 30 embracing the axle 19 1 providing a pivotalconnection 31 for the links 32 which in turn are pivotally connected, bymeans of a pin 33, to the links 34: pivotally connected withtheirupperends to a clamping member 35 secured to the frame 5 ofthe'vehicle. Ofthesetoggles, one is disposed at the fore part and the other one, ininverted position, at the rear part.

Evidently, the manner of securing the air cushions, and the articulationbetween the falxgas and the vehicle frame, may be modi- It is alsoevident that various details may be changed without departing from thescope of the present invention which is clearly defined in the appendedclaim.

We claim In combination with a vehicle frame and the Wheel-axle, apneumatic device interposed between said frame and said axle andcomrising an inflatable air-cushion and an outer Jacket therefor havingbeaded edges, a flanged member secured to said Wheel-axle and engagingthe beaded edges of said jacket, a bearing member on said frame oppositesaid flanged member freely bearing on said pneumatic device, togglesbetween said frame andsaid axle in the same plane With said axlepivotally connected with said frame and said axle, additional togglesintermediate said frame and said axle disposed in a plane at rightotally connected With said frame and said axle, sliding parts pivoted tothe upper members of said additional toggles, andguides for said slidingparts provided on said frame.

In testimony whereof We affix our signatures. v v
